Description: A validation schema is a framework that defines the structure and rules for validating data in software applications. This schema establishes specific criteria that data must meet to be considered valid, helping to ensure the integrity and quality of information. In the context of software development, a validation schema can include data types, formats, lengths, and allowed values, as well as relationships between different fields. For example, in various applications, a validation schema can ensure that an email field contains a correct format and that an age field only accepts integer numbers within a specific range. Implementing validation schemas is crucial for preventing errors and improving user experience, as it allows for the detection and handling of incorrect inputs before they are processed. Additionally, in behavior-driven development (BDD) environments, validation schemas can be used to clearly define data expectations, thus facilitating collaboration between developers and stakeholders. In summary, a validation schema is an essential tool in modern software development, contributing to the robustness and reliability of applications.
